NCT ID NCT07164079
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether a tea made from wild blackberry root could improve thyroid health in people with Graves' disease, an autoimmune condition that causes an overactive thyroid. Forty-two adults with newly diagnosed or relapsed Graves' disease drank either the blackberry root tea or a placebo tea every day for 8 weeks. Researchers measured thyroid hormones, autoimmune markers, and thyroid structure to see if the extract had any effect.
